The model saved with H5py has very little space to take up. Before you can use H5py to save Keras trained models, you need to install h5py, and the specific installation process will refer to my blog post about H5py installation: http://blog.csdn.net/linmingan/article/details/50736300 the code to save and read the Keras model using H5py is as follows: Import h5py from keras.models import model_from_json

index is to assign an integer ID to each word in turn. Traversing all the news texts, we keep only the 20,000 words we see most, and each news text retains a maximum of 1000 words. Generates a word vector matrix. Column I is a word vector that represents the word index for I. Load the word vector matrix into the Keras embedding layer, set the weight of the layer can not be trained (that is, in the course of network training, the word vector will no l

Keras If you are using the Theano back end, you should automatically do not use the GPU only CPU, start the GPU using Theano internal command.For the TensorFlow back end Keras and TensorFlow will automatically use the visible GPU, and I need it to run only on the CPU. Three methods were found on the web, and the last one was useful to me, but the following records were also made for three: using TensorFlow

right: Actually, the right is a left-hand image on the time series of the expansion, the last moment output is the input of this moment. It is important to note that, in fact, all neurons on the right are the same neuron, the left, which share the same weights, but accept different inputs at each moment, and then output to the next moment as input. This is the information stored in the past.Understanding the meaning of "loops" is the purpose of this chapter, and the formulas and details are des
